System and method for judging connection accuracy of hard disk backboard cable

Abstract

The invention provides a system and method for judging the connection accuracy of a hard disk backboard cable. The system comprises a mainboard and a hard disk backboard, and the mainboard comprises a central processing unit, an input and output system and a substrate management controller; the hard disk backboard comprises a plurality of hard disks, a programmable logic chip, a current protection module and a display module; each hard disk is connected to the programmable logic chip through the corresponding current protection module and the display module; the programmable logic chip receives power-on information issued by the substrate management controller and powers on all the hard disks one by one; the substrate management controller receives the power-on condition of the hard disk and sends the power-on condition to the input and output system; the input-output system controls the central processor to scan whether the hard disk is normally connected; and if the connection is not normal, the programmable logic chip lights up the corresponding display module. Based on the system, the invention further provides a method for judging the connection accuracy of the hard disk backboard cable, the connection accuracy of the hard disk cable is quickly judged, and the fault reason is displayed through the flicker state of the LED.

Description

technical field [0001] The invention belongs to the technical field of server storage devices, and in particular relates to a system and method for judging the accuracy of hard disk backplane cable connection. Background technique [0002] In general, servers will be equipped with more or less hard disks for data storage, especially for storage servers. A single machine may even have more than 100 hard disks, and the hard disk backplane is used to connect the server motherboard and The carrier of the hard disk, the hard disk backplane and the motherboard are generally connected by cables. As the number of hard disks increases, the number of cables that need to be connected between the hard disk backplane and the motherboard is also increasing, which will lead to a gradual increase in the failure rate of cables due to misconnection and missing connections during the assembly process. As a result, the hard disk is out of order, not recognized and other problems. [0003] At ...

AI Technical Summary

Problems solved by technology

The current technical solution can only judge whether there are missing cables by comparing the detected number of hard disks with the default number of modified configurations. figure 1 As shown, the number of hard disks does not decrease when the cables are connected, so it is difficult to judge whether there is a wrong cable connection
